"WebA lot of work has been done to predict the apparent diffusion coefficient in porous media. Carman (1939) has shown that, in porous rock, fluids must move on the average at about 45° to the direction of flow (Figure 3‑5). Hence, when fluid has traveled a net distance, L, it has traveled an actual average distance of about √2 x L. " - Flow function coefficient 意味
